Definitions
- the present invention is directed to inspection of containers, and more particularly to methods and apparatus for inspecting the finish of containers for finish defects.
- the term "container finish” generally refers to that portion of the container which defines the container mouth.
- the finish includes that portion of the container neck having threads and/or shoulders for receiving the container cap, as well as the upper surface of the neck surrounding the container mouth against which the cap seats. It is important that the container finish be properly manufactured so that a cap may be affixed thereto to seal the container cavity against leakage and escape of carbonation, etc. during handling and storage.
- a camera which includes a plurality of light sensitive elements, i.e., pixels, oriented in a linear array parallel to the vertical axis of container rotation, is positioned to view light transmitted through a vertical strip of the container side wall.
- the output of each pixel is sampled at increments of container rotation, and event signals are generated when the magnitude of adjacent pixel signals differ by more than a preselected threshold level. An appropriate reject signal is thus produced and the defective container is sorted from the conveyor line.
- a more particular object of the invention is to provide a container finish inspection apparatus and method of the described character wherein optical transmission characteristics of a test container are obtained and compared with corresponding characteristics of a standard acceptable container, and wherein a reject signal is provided where such comparison indicates that the test container is unacceptable.
- a further object of the invention is to provide a container finish inspection apparatus and method of the described character which are economical to implement in mass production of containers, and which may be readily implemented in combination with inspection of the container body for side wall defects and the like.
- the finish of a container of transparent glass or plastic manufacture is inspected by directing a source of diffused light energy onto the container from a lateral direction while the container is held stationary and rotated about its central axis.
- a camera which includes a plurality of light sensitive elements disposed in a linear array coplanar with the container axis of rotation, is positioned at a downward angle with respect to the container axis to view diametrically opposite portions of the inside and outside surfaces of the finish wall which surrounds the container mouth.
- the camera elements are scanned at increments of container rotation, and information indicative of light intensity at each camera element is stored in a first memory as an array by element number and scan increment.
- the camera views both the inside and outside surfaces of the finish wall as the container is rotated, and corresponding finish information is stored in memory.
- test information stored in memory is compared with standard information stored in a second memory indicative of an acceptable container finish.
- standard information in the preferred embodiment of the invention is obtained in a set-up operation by scanning a standard container predetermined to possess an acceptable finish and storing such information in an array by camera element and scan increment.
- the test and standard memory arrays may then be compared to each other, and a reject signal generated when such comparison indicates a difference which exceeds a preselected operator adjustable threshold.
- the camera and light source are positioned on opposite sides of the container axis.
- Light energy "seen" by the camera is thus a complex function which depends upon the refractive characteristics of the container under test. It will be appreciated, however, that such characteristics will be generally similar for a given container configuration, with some differences associated with manufacturing tolerances, differing forming molds and differing glass runs. It is contemplated that the threshold difference between the test and standard information arrays which results in a reject signal is to be empirically determined by the operator.
- FIG. 1 is a schematic diagram of apparatus for inspecting the finish of containers in accordance with a presently preferred embodiment of the invention
- FIG. 2 is a schematic illustration of the container finish as viewed by the camera, with camera field of view superimposed thereon;
- FIG. 3 is a flow chart which illustrates operation of the invention for inspection of container finish.
- a conveyor 20 typically including a starwheel (not shown) and a slide plate 21, is so disposed and connected to a source of molded containers as to bring successive containers 22 into position at a finish inspection station 24.
- Conveyor 20 may be of any suitable type, such as those shown in U.S. Pat. Nos. 4,230,219 and 4,378,493, the disclosures of which are incorporated herein by reference, and would typically include a rotatable starwheel for bringing successive containers into position and holding the containers in fixed position during the scanning operation.
- a bottle rotating device 26 such as a drive roller is positioned to engage container 22 at station 24 and to rotate the container about its central axis 23.
- An encoder 28 is coupled to the container rotation mechanism to provide signals indicative of increments of container rotation.
- a detector 30, such as a limit switch, is positioned to provide a signal indicative of presence of container 22 at station 24.
- container 22 is illustrated as a molded glass bottle having a container body 32 and a generally cylindrical neck 34 which projects upwardlly from the body shoulder 37.
- the portion of the container finish inspected in accordance with the present invention includes the upper portion of neck 34 which terminates in a cap sealing surface 36.
- a helical thread 38 is integrally molded onto the outer surface of the finish wall which surrounds the container mouth, and a lip or shoulder 40 is likewise formed on the finish wall outer surface over which a cap skirt may be crimped in the usual manner for affixing the cap to the container.
- the present invention is adapted to inspect that portion of the container finish to which the cap is to be affixed.
- a light source 42 is positioned to direct diffused light energy onto the container finish from a direction generally lateral to container axis 23.
- Light source 42 includes one or more lamps 44 and a diffuser plate 46.
- a camera 48 is positioned on the side of axis 23 opposite to light source 42.
- Camera 48 includes a plurality of light sensitive elements or pixels 52 (FIG. 2) disposed in a linear array 50 having a lengthwise dimension coplanar with axis 23 and directed downwardly toward the container mouth at an angle 54 with respect to the container axis.
- a lens 56 focuses the field of view of camera linear array 50 in the manner illustrated in FIG.
- element array 50 includes two hundred fifty-six elements 52 having a composite linear field of view which extends at least from the opposite edge of sealing surface 36 to the adjacent lower edge of shoulder 40. (It will be appreciated, of course, that the invention is in no way limited to the particular finish configuration shown for illustration purposes in the drawings.)
- An information processor 62 receives a signal from detector 30 indicative of presence of a container 22 at inspection station 24, and signals from encoder 28 indicative of increments of container rotation.
- Light sensitive elements 52 of camera array 50 are likewise individually coupled to information processor 62 for providing thereto respective signals indicative of the intensity of light incident on each element.
- Information processor 62 is connected to an object array memory 64 and to a standard array memory 66, and has an output for providing a reject signal to container sorting apparatus (not shown).
- Each array memory 64,66 is an N ⁇ M array memory, where N is equal to or greater than the number of elements or pixels 52 in camera array 50, and M is equal to or greater than the number of scan increments for one complete rotation of container 22. In the preferred embodiment of the invention, two hundred fifty-six elements or pixels 52 are provided in array 50, and two hundred fifty-six increments per container rotation are employed, each memory 64,66 thus containing an array of at least 256 ⁇ 256 memory word locations.
- FIG. 3 is a flow chart which illustrates operation of information processor 62 for inspecting the finish of container 22.
- information processor 62 scans each element 52 of camera array 50 at each increment of container rotation and stores information in object array memory 66 as a function of corresponding light intensity at each array element.
- container 22 is selected to possess a known acceptable container finish, and the information obtained in each scan is averaged over several scans and then stored in standard array memory 66.
- Standard array memory 66 thus contains a complete array of average intensities, by camera element and scan increment, for a container having an acceptable finish.
- the object or test array in memory 64 is compared, following completion of container rotation and scan, with the corresponding standard information stored in memory 66.
- memories 64,66 contain corresponding arrays for comparison purposes, such arrays need not necessarily register with each other since container finish scans do not begin and end at a predetermined fixed position circumferentially of the container axis. Stated differently, each container scan begins at a random angular location circumferentially of the container axis. However, for a given container design configuration, the array patterns will remain substantially identical. It is therefore only necessary to translate or shift data stored in object array memory 64 until the pattern of data stored therein generally registers or corresponds with that stored in standard array memory 66, so that the data may then be compared to determine if individual or groups of data stored in object memory 64 indicate a defective container.
- Such comparison preferably includes a first comparison of data at individual array locations to determine if test and standard data differ from each other by an operator adjustable threshold difference. A second comparison is then implemented to determine if the average or weighted intensity of the entire data pattern differs from the standard pattern by more than an operator adjustable difference. If either or both of such comparisons indicate an excessive difference, the reject signal is set, and processor operation recycles to await receipt of a subsequent container at the inspection station.
